The study assessed the turntaking skills and pragmatic language skills of 4 mildly to moderately developmentally delayed children (ages 2 and 3) and 14 nondelayed controls. Developmentally delayed children exhibited appropriate turntaking skills but a higher proportion of gestural in contrast to verbal responses to the pragmatic language tasks.…

This study evaluated the extent to which measures of lexical diversity (type-token ratio and number of different words produced) differentiated 25 children (mean age 59 months) with specific language impairment (SLI) from typical children. Analysis of utterance samples revealed that SLI children did not differ on type-token ratio but did use…

A plural elicitation task and a nominal compounding task were administered to 18 children (age 5-6 years) with specific language impairment (SLI) and 2 control groups. SLI children's performance was affected by input frequency; three explanations within a model of linguistic normalcy are proposed to account for this frequency effect. (Author/DB)

Parental responses to grammatically correct and incorrect child utterances were observed in free-play interactions of two groups, each containing 10 parents and their language learning children. Group 1: 21-26 months old, with MLU's between 2 and 2.5 morphemes. Group 2: 34-40 months old, with MLU's between 3 and 3.5 morphemes. (Author/BN)

Explores in three experiments development of three linguistic aspects of "more" in children's speech. Experiment 1 examined nature of early semantic content of "more;" Experiment 2, the child's differentiation of mass "more" from count "more"; and Experiment 3, the child's use of "more" as a…

Reports outcomes of three experiments in which children were taught a sentence form that they did not as yet understand. Investigates whether (1) acquisition of word order relations for sentence form would be affected by pragmatic ordering principles and (2) whether referent animacy would be included in children's rules for word order. (Author/BE)

The gesture systems developed by 10 deaf children, each incapable of acquiring a conventional spoken language naturally and not exposed to a conventional manual language by their hearing parents, were compared and contrasted to both the speech and the gesture systems developed by three hearing children learning English. (Author/BE)

The study found that 8 language-impaired 3-year-old children were less likely than 10 normally developing children to apply unusual sound changes to words with the potential for homonymy, suggesting they are limited in their ability to capitalize on the phonetic regularities of language. (Author/DB)

Assesses whether 30 children aged three-five years had a preferred direction in responding to "when"-questions and whether this preference could be influenced by story structure. Results indicated that children showed a preference for "after"-type responses and that productions of "before" were more likely to be…

Thirty-four typically developing children (ages 3-6) participated in a multi-trial word-learning task involving nonwords of varying phonotactic probability. Results indicated that common sound sequences were learned more rapidly than rare sound sequences across form and referent learning. Also, phonotactic probability appeared to influence the…

The study examined the use of primary sentence stress by seven preschool autistic children with mean length of utterance (MLU) scores between 1.9 and 4.1 morphemes with normal and aphasic subjects serving as controls. Differences were seen in the number of correct responses and in the pattern of stress misassignment. (Author/DB)

Two studies examined word frequencies in toddlers' lexicons using the Language Development Survey (LDS). In Study 1, a high degree of consistency in LDS word frequencies was found in the lexicons of 758 24-month-olds. In Study 2, LDS word frequencies in 40 late talkers found both lexicon size and age of subject influenced the degree of consistency…

The study examined adult-child interactions during conversation with respect to the effects of adult paralinguistic speech variations on the speech production of four four-year-old children. Analysis indicated that each child's response time latency (RTL) was significantly longer when the experimenter's RTL was longer. (Author/DB)

The phonological competence of 4 children, ages 5-7 years old, with a diagnosis of developmental apraxia of speech (DAS), was contrasted to that of 4 normal children. The DAS children revealed a severe deficit in rhyming ability. Results suggest that DAS is a fundamental disorder of the segmental phonological level of language. (Author/DB)

This study examined how five normally developing two-year-old children manage the relationship between phonetic production and production of word combinations in their spontaneous speech. Results revealed tradeoffs between complexity of word combinations and both accuracy of consonant production and phonetic complexity of individual lexical items.…
